It's 20,000 B.C. and you are the leader of a small band of clansmen surviving in the ice age. You live in tundra and winter is coming. How will your people survive? Where will you live? What will you eat during the winter? What will you wear and what tools will you have? There's a great timeline included that begins 6 million years ago and stretches to 4,000 years ago. There's even a pictue of an ivory carving tht is 'thought to be about 25,000 years old.' Coool!
